Here's the map:
It looks like the two circled areas are the only two ways up to the unexplored areas, going through the unsolved room to the right and then teleporting along to the left to the other unsolved rooms.. One is a long, dark vertical shaft with no-teleport marks, so that's the way down. The other way is at the top of this room:
This room seems impossible to climb, requiring split-second reflexes to avoid either falling off the elevator or being caught in the current and pushed down into the room below. My experience has been that rooms that seem to require impossible reflexes actually have a simpler solution. I'm stumped, though, and as you can see it's the only terminal I haven't yet reached.
